## 📦 补丁 1: 分块读取与流式传输 **项目仓库**: http://10.2.0.100:8989/daotong/lobster-memory-sync.git
**维护者**: 道童
### 问题 **版本**: 1.0.0
- 如果龙虾的记忆文件(比如某些 Log 或向量快照)超过 50MB **发布日期**: 2026-04-05
- 一次性 GET /api/diff 会让后端内存瞬间飙升
### 解决方案
- **流式读取**:使用 8KB 分块读取大文件,避免一次性加载到内存
- **流式哈希计算**:直接从文件流计算哈希,无需加载完整内容
- **差异对比限制**:大文件只显示头尾各 500 行,中间省略
### 实现细节
```python
# services.py
class FileScanner:
chunk_size = 8192 # 8KB 分块读取
def read_file_chunked(self, file_path: Path) -> str:
"""分块读取文件"""
content_parts = []
with open(file_path, 'r', encoding='utf-8', errors='ignore') as f:
while True:
chunk = f.read(self.chunk_size)
if not chunk:
break
content_parts.append(chunk)
return ''.join(content_parts)
def read_file_stream(self, file_path: str) -> Iterator[str]:
"""流式读取文件(用于大文件传输)"""
with open(file_path, 'r', encoding='utf-8', errors='ignore') as f:
while True:
chunk = f.read(self.chunk_size)
if not chunk:
break
yield chunk
def compute_hash_stream(self, file_path: Path) -> str:
"""流式计算文件哈希(避免大文件内存问题)"""
hash_obj = hashlib.sha256()
with open(file_path, 'rb') as f:
while True:
chunk = f.read(self.chunk_size)
if not chunk:
break
hash_obj.update(chunk)
return hash_obj.hexdigest()
class DiffChecker:
def get_file_diff(self, local_content: str, db_content: str, max_lines: int = 1000) -> Dict:
"""获取文件差异(支持大文件限制)"""
local_lines = local_content.split('\n')
db_lines = db_content.split('\n')
# 限制行数(大文件只显示头尾)
if len(local_lines) > max_lines:
local_head = local_lines[:max_lines//2]
local_tail = local_lines[-max_lines//2:]
local_lines = local_head + ['... (中间省略 {}) 行 ...'.format(len(local_lines) - max_lines)] + local_tail
```
### API 更新
```http
#
GET /api/diff/?lobster_id=daotong&file_path=large-file.log&chunked=true
```
---
## 📦 补丁 2: .lobsterignore 机制
### 问题
- 临时文件(如 .DS_Store、日志缓存不需要进数据库
- 手动维护一个排除列表会更清爽
### 解决方案
- 创建 `.lobsterignore` 文件(类似 `.gitignore`
- 扫描时自动跳过匹配的文件
- 提供默认忽略规则
### 实现细节
```python
# services.py
class IgnorePattern:
""".lobsterignore 模式匹配器"""
def __init__(self, base_dir: Path):
self.base_dir = base_dir
self.patterns = []
self.load_patterns()
def load_patterns(self):
"""加载 .lobsterignore 文件"""
ignore_file = self.base_dir / '.lobsterignore'
if ignore_file.exists():
with open(ignore_file, 'r', encoding='utf-8') as f:
for line in f:
line = line.strip()
# 跳过空行和注释
if line and not line.startswith('#'):
self.patterns.append(line)
# 添加默认忽略规则
default_patterns = [
'.DS_Store', '.git', '.gitignore', '__pycache__',
'node_modules', '*.pyc', '*.pyo', '*.log',
'*.tmp', '*.temp', '*.bak', '.vscode', '.idea'
]
for pattern in default_patterns:
if pattern not in self.patterns:
self.patterns.append(pattern)
def is_ignored(self, file_path: Path) -> bool:
"""判断文件是否被忽略"""
relative_path = file_path.relative_to(self.base_dir)
for pattern in self.patterns:
# 匹配文件名
if fnmatch.fnmatch(file_path.name, pattern):
return True
# 匹配相对路径
if fnmatch.fnmatch(str(relative_path), pattern):
return True
# 匹配目录
if pattern.endswith('/') and fnmatch.fnmatch(str(relative_path.parent), pattern.rstrip('/')):
return True
# 递归匹配子目录
if pattern.startswith('*/'):
parts = str(relative_path).split(os.sep)
for i, part in enumerate(parts):
if fnmatch.fnmatch(part, pattern[2:]):
return True
return False
```
### 示例文件
```bash
# .lobsterignore
# 系统文件
.DS_Store
.Thumbs.db
# IDE 和编辑器
.vscode/
.idea/
*.swp
# Python
__pycache__/
*.pyc
*.log
# Node.js
node_modules/
# 临时文件
*.tmp
*.bak
```
### API 更新
```http
#
GET /api/ignore/patterns/
#
POST /api/ignore/reload/
```
---
## 📦 补丁 3: 操作溯源Audit Log
### 问题
- 万一哪天点错了,无法查到是哪次操作导致的
- 需要记录操作历史,方便追溯问题
### 解决方案
- 新增 `SyncHistory` 模型
- 记录每次同步操作的详细信息
- 提供历史查询 API
### 实现细节
```python
# models.py
class SyncHistory(models.Model):
"""同步操作历史记录"""
ACTION_CHOICES = [
('sync_to_db', '同步到数据库'),
('sync_to_local', '同步到本地'),
('auto_sync', '自动同步'),
('manual_merge', '手动合并'),
]
STATUS_CHOICES = [
('success', '成功'),
('failed', '失败'),
('partial', '部分成功'),
]
lobster_id = models.CharField(max_length=50, help_text='龙虾ID')
file_path = models.CharField(max_length=500, help_text='文件相对路径')
action = models.CharField(max_length=20, choices=ACTION_CHOICES, help_text='操作类型')
status = models.CharField(max_length=20, choices=STATUS_CHOICES, help_text='操作状态')
old_version = models.IntegerField(null=True, blank=True, help_text='操作前版本')
new_version = models.IntegerField(null=True, blank=True, help_text='操作后版本')
old_hash = models.CharField(max_length=64, null=True, blank=True, help_text='操作前哈希')
new_hash = models.CharField(max_length=64, null=True, blank=True, help_text='操作后哈希')
file_size = models.IntegerField(default=0, help_text='文件大小(字节)')
operator = models.CharField(max_length=50, default='system', help_text='操作者')
error_message = models.TextField(null=True, blank=True, help_text='错误信息')
execution_time = models.FloatField(default=0, help_text='执行时间(秒)')
created_at = models.DateTimeField(auto_now_add=True, help_text='操作时间')
# services.py
class AuditLogger:
"""操作日志记录器"""
def log_sync_action(
self,
lobster_id: str,
file_path: str,
action: str,
old_version: int = None,
new_version: int = None,
old_hash: str = None,
new_hash: str = None,
file_size: int = 0,
operator: str = 'system',
status: str = 'success',
error_message: str = None,
execution_time: float = 0
):
"""记录同步操作"""
self.model.objects.create(...)
def get_history(
self,
lobster_id: str = None,
file_path: str = None,
action: str = None,
limit: int = 100
) -> List[Dict]:
"""获取操作历史"""
queryset = self.model.objects.all()
# 过滤和排序...
```
### 使用示例
```python
# views.py
@api_view(['POST'])
def sync_to_db(request):
"""同步到数据库(带操作日志)"""
audit_logger = AuditLogger()
start_time = time.time()
try:
# 执行同步操作...
execution_time = time.time() - start_time
# 记录成功日志
audit_logger.log_sync_action(
lobster_id=lobster_id,
file_path=file_path,
action='sync_to_db',
old_version=old_version,
new_version=new_version,
old_hash=old_hash,
new_hash=file_hash,
file_size=record.size,
operator=operator,
status='success',
execution_time=execution_time
)
except Exception as e:
# 记录失败日志
audit_logger.log_sync_action(
lobster_id=lobster_id,
file_path=file_path,
action='sync_to_db',
operator=operator,
status='failed',
error_message=str(e),
execution_time=execution_time
)
```
### API 更新
```http
#
GET /api/history/?lobster_id=daotong&file_path=MEMORY.md&limit=50
```
### 历史记录示例
```json
{
"success": true,
"data": [
{
"id": 1,
"lobster_id": "daotong",
"file_path": "MEMORY.md",
"action": "sync_to_db",
"action_display": "同步到数据库",
"status": "success",
"status_display": "成功",
"old_version": 1,
"new_version": 2,
"old_hash": "abc123...",
"new_hash": "def456...",
"file_size": 1234,
"operator": "逍遥子",
"error_message": null,
"execution_time": 0.123,
"created_at": "2026-04-05T12:00:00Z"
}
]
}
```
---
## 📋 数据库迁移
需要执行数据库迁移以创建 `SyncHistory` 表:
```bash
# 进入后端容器
docker exec -it lobster-backend bash
# 创建迁移
python manage.py makemigrations memory_app
python manage.py migrate
```

- **正则表达式**`re:.*\.log$` 匹配日志文件
- **通配符**`*.pyc`, `node_modules/` 匹配目录和文件
- **默认规则**:自动过滤 `.git`, `__pycache__`, `.DS_Store`
### 3. 属性目录结构
- **嵌套属性**:使用点号分隔的键名(`author.name`, `metadata.tags`
- **类型支持**string, integer, float, boolean, json
- **分类管理**:支持属性分类和元数据
- **索引优化**:快速查询属性
### 4. 审计日志
- **完整记录**:操作人、操作时间、数据源、变动行数
- **变更追踪**:属性变更记录
- **执行时间**:精确到毫秒
- **历史查询**:支持按文件、操作类型查询
### 5. 冲突判定
- **7 种状态**consistent, local_newer, db_newer, conflict, hard_conflict, local_only, db_only
- **HARD_CONFLICT**:版本 > 1 且 1 小时内更新
- **智能判断**:基于版本号和时间戳
### 6. 丝滑前端

# 重新登录或运行
newgrp docker
# 验证
docker ps
```
### 安装部署
#### 1. 克隆项目
```bash
# 克隆仓库
git clone https://xjp.datalibstar.com/daotong/lobster-memory-sync.git
cd lobster-memory-sync
```
#### 2. 配置环境变量
创建 `.env` 文件(可选,用于覆盖默认配置):
```bash
# 数据库配置
DB_NAME=lobster_memory
DB_USER=postgres
DB_PASSWORD=your_secure_password
# 龙虾记忆目录路径
LOBSTER_MEMORY_BASE=/path/to/lobster/memory
# 前端配置
REACT_APP_API_URL=http://localhost:8087/api
# 端口配置
FRONTEND_PORT=8086
BACKEND_PORT=8087
POSTGRES_PORT=5432
```
#### 3. 修改 docker-compose.yml
根据实际环境修改以下配置:
**Q: 如何修改龙虾记忆目录?**
A: 修改 `docker-compose.yml` 中的挂载路径:
```yaml ```yaml
services:
backend: backend:
volumes: volumes:
# 挂载龙虾记忆目录(只读) - /your/path/to/lobster/memory:/app/memory_files:ro
- /home/node/.openclaw/workspace/daotong:/app/memory_files:ro
``` ```
**注意事项:** **Q: 如何配置 .lobsterignore**
-`/home/node/.openclaw/workspace/daotong` 替换为实际的龙虾记忆目录路径 A: 在龙虾记忆目录创建 `.lobsterignore` 文件,参考 `.lobsterignore.example`
- 使用 `:ro` 只读挂载,确保安全性
#### 4. 构建并启动服务 **Q: 内存占用过高怎么办?**
A: 系统已限制最大内存 256MB自动清理缓存。如仍有问题检查是否有大文件正在处理。
```bash **Q: 如何查看操作日志?**
# 构建镜像 A: 访问 `GET /api/history/` 接口,支持按文件、操作类型筛选。
docker-compose build
# 启动所有服务(后台运行)
docker-compose up -d
# 查看服务状态
docker-compose ps
# 查看日志
docker-compose logs -f
```
#### 5. 初始化数据库
```bash
# 等待数据库启动
sleep 10
# 执行数据库迁移
docker-compose exec backend python manage.py migrate
# 创建超级用户(可选)
docker-compose exec backend python manage.py createsuperuser
```
### 验证部署
#### 1. 检查服务状态
```bash
# 查看所有容器状态
docker-compose ps
# 预期输出:
# NAME STATUS
# lobster-postgres Up
# lobster-backend Up
# lobster-frontend Up
```
#### 2. 测试后端 API
```bash
# 测试 API 健康检查
curl http://localhost:8087/api/
# 测试文件扫描
curl "http://localhost:8087/api/scan/?lobster_id=daotong"
```
#### 3. 访问前端
打开浏览器访问:
- http://localhost:8086
**预期效果:**
- 能够看到文件树展示
- 能够点击文件查看差异对比
- 能够执行同步操作
### 生产环境配置
#### 1. 使用环境变量文件
创建 `.env.production` 文件:
```bash
# 生产环境配置
DB_NAME=lobster_memory_prod
DB_USER=postgres
DB_PASSWORD=<强密码>
DB_HOST=postgres
# 龙虾记忆目录
LOBSTER_MEMORY_BASE=/var/lib/lobster/memory
# 前端 API 地址
REACT_APP_API_URL=https://api.yourdomain.com/api
# 端口配置
FRONTEND_PORT=8086
BACKEND_PORT=8087
POSTGRES_PORT=5432
```
#### 2. 配置 Nginx 反向代理
创建 `nginx.conf`
```nginx
upstream backend {
server localhost:8087;
}
upstream frontend {
server localhost:8086;
}
server {
listen 80;
server_name yourdomain.com;
# 重定向到 HTTPS
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl http2;
server_name yourdomain.com;
# SSL 证书配置
ssl_certificate /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomain.com/privkey.pem;
ssl_protocols TLSv1.2 TLSv1.3;
ssl_ciphers HIGH:!aNULL:!MD5;
# 前端静态资源
location / {
proxy_pass http://frontend;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
}
# 后端 API
location /api/ {
proxy_pass http://backend/api/;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
}
```
#### 3. 启用 HTTPS
使用 Let's Encrypt 获取免费 SSL 证书:
```bash
# 安装 certbot
sudo apt-get install certbot python3-certbot-nginx
# 获取证书
sudo certbot --nginx -d yourdomain.com
# 自动续期
sudo certbot renew --dry-run
```
#### 4. 配置数据库备份
创建备份脚本 `backup.sh`
```bash
#!/bin/bash
BACKUP_DIR="/var/backups/lobster-memory"
DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_FILE="$BACKUP_DIR/backup_$DATE.sql"
# 创建备份目录
mkdir -p $BACKUP_DIR
# 执行备份
docker-compose exec -T postgres pg_dump -U postgres lobster_memory > $BACKUP_FILE
# 压缩备份
gzip $BACKUP_FILE
# 删除 7 天前的备份
find $BACKUP_DIR -name "backup_*.sql.gz" -mtime +7 -delete
echo "Backup completed: ${BACKUP_FILE}.gz"
```
添加定时任务:
```bash
# 编辑 crontab
crontab -e
# 每天凌晨 2 点执行备份
0 2 * * * /path/to/backup.sh
```
### 更新部署
#### 1. 拉取最新代码
```bash
git pull origin master
```
#### 2. 重新构建镜像
```bash
docker-compose build
```
#### 3. 重启服务
```bash
docker-compose up -d
```
#### 4. 执行数据库迁移(如有)
```bash
docker-compose exec backend python manage.py migrate
```
### 监控与维护
#### 查看服务日志
```bash
# 查看所有服务日志
docker-compose logs -f
# 查看特定服务日志
docker-compose logs -f backend
docker-compose logs -f frontend
docker-compose logs -f postgres
# 查看最近 100 行日志
docker-compose logs --tail=100 backend
```
#### 查看资源使用
```bash
# 查看容器资源使用情况
docker stats
# 查看磁盘使用
docker system df
# 清理未使用的资源
docker system prune -a
```
#### 数据库维护
```bash
# 进入数据库容器
docker-compose exec postgres psql -U postgres -d lobster_memory
# 备份数据库
docker-compose exec postgres pg_dump -U postgres lobster_memory > backup.sql
# 恢复数据库
docker-compose exec -T postgres psql -U postgres lobster_memory < backup.sql
```
### 故障排查
